Two parts of 6-chloro-2-ethyl-1H-imidazo[4,5-b]quinoxaline was suspended in 40 parts of methanol. One part of concentrated HCl was added to give a solution. A solid formed at once and the slurry was cooled and filtered to give 2 parts of 6-chloro-2-ethyl-1H-imidazo[4,5-b]quinoxaline hydrochloride, m.p. 280°-282°.
